The concept of the trashcan does not exist in Command-line interface (CLI). If you have deleted an important file by mistake with the rm command, it would be difficult to restore. Then, it's this gomi. Unlike rm command, it is possible to easily restore deleted files because gomi have the trashcan for the CLI. It is also possible to work with trashcan for Graphical user interface (GUI). *1 gomi means a trash in Japanese.
